The present invention concerns a prefabricated road marking capable of resisting to the passage of snowsweeping machines and the like, generally termed snowplows, comprising snow blades sliding on the road surface. …<??>The present invention concerns also an improvement to methods and apparatuses for the laying down, on the road surfaces, of said road marking material. …<??>The road marking tape (10) of the present invention is provided, at its upper surface, with retroreflecting optical elements (6) for providing night-time visibility, and with protruding components in the general form of rails (12), of highness at least equal to said of the retroreflective optical elements, which rail components are effective to protect said retroreflective optical elements from the impact of snowplowing equipment travelling and scraping along the road surface; in accordance with the present invention, the road marking tape material is further provided, at least in its operative condition as laid-down on the road surface, with a compressible elastomeric component (3) which under the impact of said snowplowing means passing thereover, will cause the projecting portions of the tape to sink or be lowered onto the road pavement level (7) or below said level, whereby to still further and more effectively protect the tape surface and the optical elements protruding therefrom from damage by the snowplowing equipment. |
